Hi all. I'm trying to draw some text on a canvas, and when I go to draw the text, I am getting the errors above and the text is rendered as square boxes. I draw other text in this program on a canvas, and that works fine every time, but I have no idea why I could be having this problem. Does anyone have any idea?

The 'out of memory' errors makes me wonder if you're running out of resources -- too many fonts/images/widgets etc. Try putting your snippet in a standalone program and see if it works. If it works in the standalone then look at the SWT Sleak tool to track down the errant allocations.
Brian.
