Office 2003 (on WinXP) hangs after start

I have a urgent problem with a PC with Windows XP SP2 and Office 2003 SP3. Windows XP starts without problems. Scandisk reports no problems. No Virus and no detected spyware (tested with Norton Antivirus and AdAware). Temp directory has been cleaned. Description: If i start ANY Office application like Word, Excel, and so on... The Application starts but then immediatly hangs for about 1minute. After that minute you can continue to work with that program without any problems.... until you close it and open it again. For example in Excel... You start it... the window and menu will be created and you'll see a empty Table. But then you can't click any Button, nor type any text in Excel for about 1min. (You can still work with other applications! Only Excel is "locked") After that minute, everything is fine. This Problem occours with all Office Programs and with the Internet Explorer 6. Any Ideas how to fix that? ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition, as follows (depending on the nature of the deliverables): a) For web sites or other server-side deliverables intended to only ever exist in one place in the Buyer's environment--Deliverables must be installed by the Seller in ready-to-run condition in the Buyer's environment. b) For all others including desktop software or software the buyer intends to distribute: A software installation package that will install the software in ready-to-run condition on the platform(s) specified in this bid request. 3) All deliverables will be considered "work made for hire" under U.S. Copyright law.
