Menus : popup invisible

[unknown]

QM 2.3.0.10. This happens so now and then: A menu when evoked (eg. by a key combination as a trigger) or a drop down menu in the QM editor does not appear.
However parts of the menu do appear where you hover your mouse over the at first invisible menu parts.

A restart of QM doesn't help, only a system restart cures it.

Thank you,

Like something does not delete unused GDI objects. Look maybe your macros don't call DeleteObject, DestroyIcon etc where needed.
