OK, I've found out the cause of this... ICONPACKAGER 3.00.090.......
Since my last post, I've totally reformatted, then I've been installing One ODNT application, then rebooting, then testing computer, then installing next application, rebooting, testing etc.
I only get the problems after the latest release of IconPackager (v3.00.090) has been installed.
I think it would be a very good idea for stardock to fix this ASAP, i've spent literally hours over the past couple of days messing around, almost getting a refund at one point when the problem is caused by only one of the applications.
Fortunately, I took the time to test the computer with the different programs, I had half suspected it to be IconPackager, after reading someone elses post on here about a program not loading after installing this.
Is there anywhere I can find the changelogs for IconPackager, so that when a new version is released I can find out if this problem has been corrected before I install it?
Thanks..
