Flexbar Sandboxie Compatibility

[Newbeak]

I have SB 3.5.4 running on a 64 bit Windows 7 Home Premium installation.I recently upgraded to Firefox 5 Beta because of an intermittent problem with my printer,which was cured by Firefox 5. The problem is,a lot of my add-ons are not compatible with FF 5,and to replace one of them,All In One Sidebar,I installed a similar add-on called Flexbar,which automatically hides the sidebar when the cursor is not touching it.My problem is that Flexbar works fine for a while,but after an hour or so,it stops working (the sidebar disappears). I have found if I clear the contents of Sandboxie,this restores the Flexbar to normal operation.I was wondering if Sandoxie was somehow involved here,or it was an unrelated problem.Does anyone have any suggestions?
Thanks

You can try to set "allow direct access to entire Firefox profile" in Sandboxie,

Sandbox Settings > Applications > Web Browser > Firefox

And if this makes the problem go away, then chances are Sandboxie has something to do with this.
