I have a final question that I'd like to ask you... I developed and tested the add-in on Ubuntu Feisty that comes with OOo 2.2.0. The add-in seems to work perfectly, but the function wizard is incredibly sluggish for my add-in (and not for the regular OOo add-in)... For example, when I select a parameter in the add-in, CPU usage goes to 100% and it takes 5-10s before the new parameter and the corresponding cell ranges are highlighted - and the examples are all very small. But if I update the add-in parameters directly without the function wizard it works fast and smoothly, so it's not just simply Python being slow.
Can anyone think of a potential error in the add-in that would cause this? If I can solve this problem also, I will be happy to the add a small Python example to the wiki in return for all your help... thanks Joachim
