Firefox 4 and S.B

Hello, yesterday I upgraded from firefox 3.16 to 4.01
When I open a sandboxed firefox the first time from booting, It's taking a minute to load. However if i disable forced programs, while I'm waiting, and also start firefox unsandboxed, it loads instantly.
So, just to clarify, when i start firefox sandboxed, the tray icon is dotted and firefox is shown running in the S.B menu, however its taking an eon to show.
Funnily enough this only happens after booting.Once it has eventually loaded, if i close the browser and reopen it loads straight away.
Has anyone else had this.
I am using S.B 3.52
I will try 3.54 later
Many thanks
P.S this only affects F.F , chrome loads instantly


EDIT
I installed S.B 3.54 and all seems well, Sorry to waste your time. I should of tried before posting.

 

It may have something to do with upgrading. I did a straight install of Firefox 4 on a laptop and have not had any issues with Sandboxie so far. Maybe you should try reinstalling and see if that helps.

 

Possibly. Thanks for that. Updating S.B seems to have improved things a lot.If the problem returns, I will take do as you say. Thank you very much
