I've in my program label+panel+image_control

The label size varies according to the included data and I've to show it programatically as soon as the user move the cursor over the image (using the mousemove event), but unfortunately the label seems to be unstable as it appears in different locations in my form & sometimes hanging although i specify the location to appear in.

How show the frame in front of the panel even though the frame sometimes may cross the limits of the panel control???
