Help with Stop Record command on Win32 machines

[Devin Asay]

Bill,

I've run into a couple of problems with Windows and QuickTime over the last couple of years. I don't know if this will apply to you, but it may be worth checking out.

1. I saw some problems with LC apps crashing on Windows XP with QT 7.6.4 installed. Older and newer versions seemed not to be affected. If you have access to the Quality Control Center you can see bug report at http://quality.runrev.com/show_bug.cgi?id=8420

2. In the read me file for one of my apps that lets users view QuickTime videos, I have the following notice:

Known Problem on the Windows Version:
--------------------------------------
On some Windows systems the [LiveCode app] might
crash when you try to view video recordings. If this happens, try the
following:

Go to your Control Panels and open the QuickTime control panel.
Click on the Advanced tab.
Under the Video section, select Safe Mode (GDI only).
The videos play normally after you make this change.

Again, don't know if this could be your problem, but it might give you a lead.

Regards,

Devin
