Ok, sorry to reply to own post but just discovered what is causing it - it happens only when the make taskbar semi transparent setting is selected. Hope this helps bugfix. Richard Malone
Strange occurance and quite annoying. Happens when WindowFX and WB loaded at the same time. Running on Windows Server 2003 R2 SP2, all software is up to date beta. Only occurs when per-pixel alpha blended themes are used. See the following image for an example. This could equally be a problem with WindowBlinds, so let me know if I should post it there. Thanks for anyhelp, and for great software. Richard Malone
