PropertySheet and Popup Windows

[conio]

Hello people:rose:, i have a rather unique problem. in my application i have two tierd property sheets. (on the main dialog i have a property sheet with some pages and on each of the pages i have a property sheet and some pages) all the property sheets are created at run time and the program wortks fine. The problem starts when i try to add any control on the base dialog. in case a control is added, the program just doesnt pop any windows (file dialog for example) the whole application just hangs:((. Can somebody tell me as to why this may be happening and what may be the possible solution. The Debugger
