I tried to enable the RTL support on rad tree, and found that the context menu suddenly got the 100 % width of page -
please see the attached image .
When I tested it on other machine, I found that context menu was ok.
The difference was that on machine with problematic context menu I had IE6 , and on the second machine it was IE8 and chrome.
Is it really could be a problem with IE6 ? Other problem ?
