Simple Graphics program behaving differently on differnt machines

[guest087123]

I have made a simple drawing application and changed the cursor to be a bitmap which I made in c sharp. The cursor is supposed to change colors when a button is clicked on the form. For example click the red button on the form and the cursor will change to red and then the user can draw lines in red when holding down the right button of the mouse. When I am at home it works no problem but when I'm on a machine in university the cursor stays black when I click on the colored button but the lines being drawn do change color. Both machines use Visual Studio 2008. Does anybody know what could be wrong?

Sounds like trouble in your cursor bitmap code. Could be related to the windows theme I would think too

It was a problem with the theme on the class computers. Just set it to the xp theme and it worked as normal.
Thanks alot
