Normally the panel is not resizable and works correctly with correct size.

But using the panel in ID CC2018 it is frequently open to a larger size than necessary and growing at every launching until it becomes unusable.

To adjust the size, it is necessary to reset the preferences of ID

Some ideas on how to solve the problem?

Thanks
