[Qtce-preview-feedback] Sub-menus stop displaying

[George H. Locktish]

I have noticed that sometimes sub-menus for my application stop
displaying.  I am using Qt on Windows Mobile 5.0 and I have an
application that has 4 top-level menu items, and each top-level menu
item has a sub-menu.  All of the menus normally display properly;
however at times some of the sub-menus will stop displaying.  Normally,
when this occurs the other top-level menu items and their sub-menu items
still function.  The only way that I have found to recover from this
situation is to stop the process and to restart the application.

 

This seems to happen most often when the software is pretty busy (for
example, the application may be in the process of painting and/or
responding to updates we have made to our item models).

 

Unfortunately, I don't have a reliable way to reproduce this issue;
however, it does happen with some regularity.
