Hi Gernot
Here is an odd one. I've transferred GLBasic to my new laptop (which uses Windows 7) and registered the product, however occasionally when trying to run my game I get an error message stating that the "Demo version can only run in 640x480" and to press a key. On pressing a key, I get the DEMO watermark on screen. However, if I exit the game then restart I get the full version again.
This has happened a few times so far.
Oh no! thank you for sharing. I'll have to get my hands on a copy of 7 quickly. Oh dear. I'll get a new PC next year or in 2 years, so that might be a problem. I see if a VM machine can do.
