Snow not shown correctly if Rate is non-zero.

[wuhu_software]

If the .XML contains a snow rate, and then you start YoWindow, the first time YoWindow attempts to render the snow, it is all bunched up on the left side of the screen for the first 20-30 pixels on the left edge of the application window. Unless you minimize to the task bar and re-open the main window, this problem is corrected.

A different but related issue occurs if you re-size and expand the YoWindow application window (in non-full screen mode) by dragging the mouse using the lower-right hand corner of the window, the newly expanded area of the screen does not render the snow. The existing section of the screen that was rendering the snow continues to do so. It appears that something needs to be adjusted if the screen is re-sized.

If you minimize YoWindow to the task bar then double click it from the task bar, when it renders again, the snow works properly in both the above described situations.

Dear Wuhu, that was a very important bug-report.
Shame on me, I have missed the snow completely while making the recent changes.

Thank you so much!
Now the error is fixed in the RC.
