Hello,

we discover a strange problem when using the UltraToolbarsManager.

On one form we have placed an UltraToolbarsManager wich contains some ribbon tabs with groups and ToolButtons. The images uses by the buttons are stored in ImageLists wich are connected via the ImageListLarge and ImageListSmall properties of the UltraToolbarsManager.

When the application is started the Windows TaskManager shows, that the memory usage is increased every time the mouse is moved over a button. It look like as if the images was loaded again and again. After a while, the buttons (no only the images!) on the ribbon group where the mouse cursor is currently oved over disapear or the ribbon groupis displayed as a red framed box with a red cross in it. After some more time when moving the mouse over the remaining buttons of other groups the application crashes.

Btw. there are no events handled when moving the mouse.

Does anyone have an idea how to solve my problem?

Best regards.
