Hi,
thank you for your quick reply, really appreciate this!
It happens to almost every program I run, yes. I tried with Word 2010, Excel 2010, PowerPoint 2010, Photoshop CS5.5, Indesign CS5.5, KeePass, TotalCommander, TrueCrypt, RealVNC Viewer, QuickPar, ImgBurn, 7-Zip, Notepad++, Miranda, Mumble, Thunderbird, FileZilla and so on. Some of them are now ok, for instance Word, Notepad++ and RealVNC.
// EDIT: Nope, Notepad++ and RealVNC had a delay again after rebooting the PC, Word came up quickly.
It even happened to cmd.exe and notepad.exe at first - this isn't anymore since today.
My network connection is cable (Unitymedia in Germany), 128mbit down / 5mbit up.
Thanks,
Alex
