I ran into the same issue when I tried to simplify the 
showing/hiding/visibility/positioning logic (make it simpler and more 
Kylix way).

All was well and working, except that I noticed that when the same hint 
window is showing for *second* time, it will seemingly freeze Lazarus - 
you must be then quick to switch to a text console and kill Lazarus to 
save your X session and a potentional reboot. If you are not quick 
enough, it will freeze your X.

My guess it is a result of IMHO somewhat complicated visibility handling.

After many hours looking at it, I decided to scrap my changes and leave 
it as it is :-(

If you manage to solve this, let us know! I just could not find the 
error :-(
