I have 4 PCs running W7 Home Premium 32 bit all with the same annoying problem. Very often when I close Windows Live Mail 2011, Microsoft Security Essentials or Word Pad the corresponding process is killed but the window will not disappear before I click the Desktop Ikon. It only happens with those 3 programs. The 4 PCs are 1 Sony Vaio Laptop, 1 ThinkPad T60 and 2 ASUS Desktop PCs. It have been the same alle the time (for more than 1 year). Everything is 100% updated. W7s are OEM Versions. The Log do not show any problems referring to this issue.
