I did a search and see this is a known problem with no reported solution. So I am posting to see if it's been addressed.
JASC Paint Shop Pro 9 crashes under Windowblinds. I am using Win 7 64 bit.
Here's the thing: I am NOT willing to update my Paint Shop to the Corel version, as I am happy with the JASC older version, and am very fast with it. No other program gives me any problems with it, so it's a deal breaker for Windowblinds. If I can't get JASC PSP to work, I will have to uninstall WB. Changing compatibility settings for PSP has no effect. Uninstalling WB fixes it.
