Hi Writeaway,
I found the solution on the website of a Belgian magazine. Since I assume you don't speak Dutch, I'll try to explain in English here.
First of all, since I don't know how familiar you are with the concept of the registry, I'd like to remind you that messing with it could be dangerous if you don't know what you're doing. You should make sure you always make a backup first!
Open REGEDIT (from command line). Find the key HKEY_CURRENT_USER, SOFTWARE, MICROSOFT, WINDOWS, SHELLNOROAM. If you open the key SHELLNOROAM, you should find (among others) the subkeys BAGMRU and BAGS. Remove those.
Now reboot Windows and restart REGEDIT. Right-click SHELLNOROAM and shoose new --> DWORD-value. Give the new value the name BagMRU Size. Then doubleclick it and set the value to 1000 (decimal). Create the same DWORD-value in SHELL (which you should find right above SHELLNOROAM).
I hope this helps! It did for me.
Greets,
Niek
