Hi,
Haven't found what the Root Cause of this problem is, however I have found a workaround:-
1) Shut down Notes completely
2) Navigate to c:\Program Files\Lotus\Notes
3) Run nlnotes.exe to start the light client
4) Set your bookmark as homepage in this client, then exit
5) Start Notes in the normal manner
It's worked on every machine I have ran the fix on. The only think I have not tested (and I doubt I will do so anyway) is to see if this is actually a permenent fix or not. I'd be interested to see if it works for you as well ndaco
