Slow context menu

I
Congratulations on this new application.
Is there any problem on having the portable version and the installation version in the same PC (Win XP)? I have the two versions of OO3, one in HDD c:\, and the portable in HDD e:\. Since I'm using the portable one, the context menus (in writer, Impress, Clac...) take a long time to open in both versions. Why?
In "installation" of 0O 3 Portable I've chose "import definitions" and follow the instructions to make the version portable a portuguese-pt one by copying the files.
