Hi iomega 55,
The provided code seems to be correct and that is why I built up a sample test demo but unfortunately to no avail - I was not able to reproduce the issue. That is why the only thing whichh I can assume that might be causing the issue (since you say that it happens only sometimes and not always) is that some js error occurs in your code while teh splitter is initializing itself and this stops its resizing. Would you please examine my tets demo and let me know whether you see the issue there (it uses your code, I removed the BorderSize=0 for demonstration purpose to show the splitter and its size)? If you do not see the issue, please tell me how to modify the code and under which browser to test and also provide reproduction steps if others than loading the page and refreshing it are needed and I will do my best to help.
