Strange Canvas repaint problem

Java on Mobile Devices J2ME
#1

Has anyone ever experienced a problem with getting the P800 canvas to repaint automatically when switching between canvases (when using display.setcurrrent(myCanvas);)? Instead of repainting properly the screen just goes white until you ‘force’ the canvas to repaint by sending a keypress. If you have not directly experienced this problem can you offer any suggestions of what might be the problem?

I thought I would try on this forum to see if anyone has any suggestions as it is unlikely it will be replied to over at the se forum.

Just had to call a dummy keypress right after the setcurrent is called for the next canvas, and in that canvas’s keypress function it is caught and forces another repaint().
