After a session of finding and editing records the 'Find' window refuses to close at some stage. The normal contents of the window are replaced by either transparency, or a copy of the Form window beneath.

Reproducible: Sometimes

Steps to Reproduce:
No known sequence of steps to reproduce this.
Actual Results:  
The 'Find' box will not close after some extensive useage of searching and editing records.

Expected Results:  
That the Find box will close at any time.

There is a pattern of misbehaviour that becomes apparent after some extended use of find-edit procedures. 
These include:

The 'Find' window cannot be closed. neither the 'Close' button nor the 'x' at top of the box will close the window, so then we roll it up to put it out of the way. Everything else is running normally.

The rolled-up window when then rolled down is just a transparent frame, the Form is seen through this
Clicking on the 'Find' (binocular' icon will then fill the frame with a section of the Form This can be dragged around with no other adverse video affects, but the contained 'Form' image remains in the window.

If the window is then rolled up, then clicking on the 'Find' icon and rolling the window down will reveal a functional 'Find' box. But this still cannot be closed. [Alternatively, rolling the window up, dragging the box around, and then rolling down again _may_ possibly also reveal a functional 'Find' box]

At this stage the 'Find' box still cannot be closed. The box will only be closed when exiting Kexi. It remains there when the current application is exited. 

Eventually we may enter a worse scenario where Kexi must be closed and restarted. This behaviour does not appear to cause specific crashes. 

I need more of these events to verify this complete sequence and determine behaviour definitively.

This bug was apparent on earlier versions.
