Matrox MMS cards and combo boxes

[foft]

We use Matrox G100 and G200 MMS cards heavily where I work. Recently all our systems are being converted to Windows XP. We have come across a problem when testing the application I wrote, which I think may be a driver issue. The problem is with ComboBox controls. When on the 2nd or 3rd monitor these seem to disappear when the list is dropped down.

Has anyone here experienced this or does anyone know of a fix?

Thanks,

Mark

Have you asked matrox tech support or posted in tech support forum?

Know this post is ancient, but for histories sake thought I should put what I found...

It turned out to be a bug in a MultiColumnComboBox we'd borrowed from CodeGuru. It was checking the width of the screen incorrectly (and a host of other bugs). Basically because XP runs our G200MMS cards in real multi-monitor mode and NT4 in stretched single-monitor mode. There are new API calls to get width of multiple monitors.
