bug (2 tabs and one is looking at Windows folder)

[UR user]

After creating a second tab, then going back to an original tab (which looks at a Windows folder), I have gotten the following error a few times:

Assertion failed!

Program: .... ultrarecall.exe
File: c:\src\boost_1_33_0\boost/shared_ptr.hpp
LIne:253
Expresion: px!=0

If I press the "retry" button, I get:

Error loading item(s): Access violation
Exception 0xc0000005 occurred in moduel .... at address 0x2decd2ba, offset 0x0002d2ba.

Thanks.
