Loading room occasionally stops

I searched the posts, but too many loadings error that none of them seems related to this one.

Problem:
When I click a room and trying to get into it, it starts loading normal, but at the last step (the bar nearly get full, from experience, I know it just need a jump to end). The page hang there.

The result is, after 1 minutes, I get back to the lobby but resolution of the game (and windows) changed.

On my xp, I need to reset the resolution of windows to make it normal, while the game ui gets either too big, or too small. In both case, you cannot continue any more. Either the join button is out of reach (out side screen) or the pointer seems in a different position from where it points to (move mouse on a button can not highlight it, while move to other position might have it highlighted).

On my win7, I have not seen a shrinked game gui, but sometimes I get a low resolution screen that makes everything very big. Win7 auto restore it resolution, however, the CF gui get very large and the button is not reachable any more.

I feel this might related to the game ends during my loading, because I notice sometimes it gets very slow to response till a game statistics gets up. However, in this case, the resolution is normal.

The solution to it is to kill the process and restart the game. Otherwise, I would not be able to logout normally.

Even when I trying to go back to a room I just quit after 10s of seconds I might get the problem.

Also, I notice some room listed (not full) but when I trying to enter, it forbid me to do so (no message like you can not enter a room when you get kicked)

MY SYSTEM:

win xp: dell vostro 1400, core 2 duo T7250, 2G memory, dedicated video card (Geforce 8400M GS 128M maybe, it is standard for that model), 16:10 screen ratio (set to 1280:800), wireless connection with strong signal level. Normally ping 19 +- 2 ms in pingtest.net. In game normally 49 ms.

win 7: lenovo ***X, core i3 ***. 6G memory, dedicate video card ( GeForce 9600 GSO 384M). 4:3 screen ratio, (1024:768). Wireless connection is not very stable, pingtest show best as 19+-3ms most of time I game, sometimes it gets to 1XX+-1XX (depends on day and time), but I think when the bug appears it should be 59 ping in game.


THE WHOLE PROBLEM IS NOT CRITICAL BUT IT IS VERY ANNOYING. I have to do lots of ctrl+alt+del recently. And xtrap would not let me to use proexp when game starts.
