Performance and Features FAQ

What's the best way to view a Glance Screen Share session?

For the fastest performance on PCs and Macs, download the free Glance software and connect with its built in viewer, by clicking G > Join Session.

Alternatively, on a Windows PC you can use Microsoft's Internet Explorer to get the free Glance viewer (350k). It's one-time install takes a few moments. Then join the session using Internet Explorer. You will connect instantly and see updates as fast as they are sent.

How much memory does Glance use?

When Glance is not in a session, it uses about the same amount of virtual memory as an instant messaging icon sitting idle (under 5MB). During a session, Glance needs as much memory as a multimedia player (15 to 20MB).

How do I let others show their screens when we're using Glance Screen Share?

Now with Glance Screen Share, you can switch presenters during a session! Co-presenters just need Glance installed before joining. They do not need a subscription.

How can I record a Glance session?

Glance solutions do not come with a recording technology. However, there are several great recording solutions that you can use with Glance solutions.

Recommended applications

For recording a Glance session, we recommend two applications.

For our PC customers, we recommend a software product called Camtasia. If you're on a Mac, we recommend ScreenFlow. Both applications let you capture what's on your screen along with your voice.

When the session is done, both programs provide the ability to to edit the content and publish it on your website in a variety of formats, such as Flash and QuickTime.

A cheaper option that can still do the job fairly well is Ink2Go, which also has annotation features. A free trial version is available.

To include everyone's voice in the recording, plug an inexpensive device from RadioShack between your phone's handset and your computer's microphone jack (usually pink-colored on a PC) and flip its switch to RECORD.

How can I get the fastest possible Glance Screen Share performance?

Below is some advice on how to get the best Glance Screen Share performance.

User friendly firewall

Start a session and look at the Session Status field in your Session Info box. If it includes the word tunneling, you may want to ask your network administrator to add a simple, secure rule to your company's firewall policy so Glance can run at peak efficiency.

Check your upload speed

Guests see changes to your screen only as fast as you can send them to Glance Screen Share. The bigger your pipe, the faster Glance Screen Share runs.

Many small business and home office networks enjoy fast download speeds, but their upload often is just a fraction as fast. Slow upload speed can cause slow Glance Screen Share performance. Check your network's performance at the Glance Screen Share System and Performance Requirements page.

Lower your host screen resolution

Glance Screen Share sends your entire screen, so reducing its resolution should improve performance. For example, a complete 1280x800 screen can be sent about 2x faster than 1920x1080.

How can guests join my session without a Session Key?

Want guests to connect super-fast? Now they can go to your Glance Address and join instantly. Use the new No Key option -- now available in Glance 2.11 for Windows PCs (download here and Glance for Macs (download here).

  2. Choose Settings.
  3. Click the Options tab.

  5. Click OK.

To join your sessions, guests just browse to your Glance Screen Share address. They join immediately after entering any contact information you might require.

Can Glance solutions transfer files?

No, Glance solutions cannot transfer files.

You can reassure your security-conscious session guests that neither person can send any files during a Glance session. Should you need to transfer files, we suggest you send the files as an e-mail attachment or provide them to your guests on your website.

We can customize your Glance web pages (where guests join and finish sessions) with your logo as well as links to files on your website. Contact Glance support for details.

Can Glance Screen Share show my spinning 3-dimensional CAD model?

Glance Screen Share always does the best it can, given the available bandwidth, processing power and the complexity of the screen being sent. If you find that performance is slow, you might try reducing the resolution of your display or having your guest use Glance Screen Share's native viewer.
