List of constraints bug

Hello,

Then property grid window is located at the bottom of the parent window and I select item with list of constraints, this list draws itself incorrectly, so user can not select some items in this list (see attached image). Please help me to solve this problem.

Hm... Can not attach any file (it is .zip and 3k size) so just describe the problem. Maximize the main frame window and dock property window at the bottom. Then you select the item with constraints list and it displayed, this list cutted along the Windows taskbar, so only a top part of the list is displayed but a bottom part (with items and bottom scroll button) is hidden and user can not select any items at the end of the constraints list.
