Program running on Win7 but wont appear on screen

I have a weird problem running Adobe GoLive CS2 (version 8) on Windows 7 - the program runs but won’t appear on screen. I don't get this issue with any other program and until this happened a few days ago the program worked fine on Windows 7. GoLive hasn’t been updated for some time but Windows 7 has….

When GoLive is started, the 'title box/splash panel' with logo and version number etc appears on screen, it shows it’s loading up various components and the icon appears on the taskbar, but no program appears on screen. It doesn't matter how many times I click on this, it wont appear on screen. If I hit Alt-Ctrl-Del and bring up Task Manager I can see it's running in the Applications tab and I can also see it's process running on the processes tab too.

I thought maybe it had gone 'off screen' so I used all the Windows 7 tips on how to bring progs back on screen but nothing works, so I don’t think it’s this.

Interestingly, when I hover over it's icon on the taskbar, and hold shift whilst clicking it to try to bring up the old-style maximise and minimise options, nothing appears - although this works with every other application.

I use two screens, so I tried changing the display to use just one - makes no difference.

I then uninstalled GoLive, rebooted and installed it again - makes no difference. I installed GoLive on a Win XP machine and it works fine.

What can I do to find out what’s going on?
