Thank you for writing us.
Unfortunately we haven`t add resizing of DeskTool panel in docking mode.
At the moment it is impossible to change the geometrical sizes of the DeskTool panel in a docking mode. Therefore many elements can cause such a problem. It is impossible to resolve this roblem by changing parameters of visual style.
We will add possibility of changing the panel sizes in docking mode in the next version of DeskTool.
There are alternative variants allowing to resolve this problem.
1. Switch the panel in float mode. In this mode Desktool will automatically fit the sizes of the panel necessary to display all objects.
2. Reorganize the DeskTool objects using the menu.
