Add Corel X4 w/SP1 to this list with all the above symptoms. Running Vista 64bit w/SP1, 22" wide screen (1680x1050), Nvidia Gforce 7600GT. Additionally, thought this may not be an issue, I use a wireless Logitech mouse (have tried several different mice). Not exactly sure at what point this got broken but worked fine when Corel X4 originally installed. This problem has arrisen very recently. Have tried F8 workspace reset, complete uninstall and reinstall. Something is stepping on a driver somewhere... just don't know how to find out which one nor how to fix it. I did install and uninstall Macromedia Flash 8 Pro on this machine. Did uninstall/reinstall of Corel after Macromedia was uninstalled. Have use several registry cleaners but as we all know, there is still Macromedia left in the registry.
Corel X3 w/SP1,2 &3 running WITHOUT problems on my WinXP (32bit) w/SP3 machine, 19" no wide screen, nvidia Gforce5200GT. I have installed and uninstalled Macromedia Flash 8 Pro, installed Adobe Flash CS3 Pro. Have not install Adobe Flash CS3 on vista box..
Hoping someone will post a solution.. Seems Corel isn't acknowledgeing the problem
PS - I too have been a loyal Corel user since ver. 1 first release.
