What steps will reproduce the problem?
1. Use a character with large bags in inventory and bank.  (Mine has four 22-slot bags in inventory and 6 20-slot bags in bank, plus 1 18-slot bag).
2. Open the bank frame and inventory frame.
3. Find which frame has higher strata by dragging the bank frame to overlap the inventory frame.
4. Position bank frame roughly 50 pixels above or beside inventory frame, not overlapping.
5. Depending on which frame has higher strata, move the lower-strata frame quickly to overlap the higher-strata frame.  Do this several times, alternating frames, until the screen freezes for 3-5 seconds minimum.
(Please provide as exact of steps as you can the better
the steps you give the easier I'll be able to reproduce
the problem and the faster it will be fixed)

What is the expected output? What do you see instead?
TBag shouldn't freeze the game when trying to change the strata while moving the frame at the same time.  I see the game freeze when I do this, and I tend to move my bank and bag frames around quite often.

What version of the product are you using?
TBag-Shefki revision 265 directly from the SVN.

Do you have an error log of what happened?
No.

Can you reproduce this problem with TBag as the only addon loaded?
Yes.

Can you reproduce this problem after renaming your stored variables file?
(WTF\Account\USERNAME\SavedVariables\TBag.lua under your WoW install, log
out of WoW, rename the file something else and log back in)
Yes.
