Possible MPLab or Equiptment Problems?

[PlaidPillagers]

Hi,

So, the default code works (the pre-compiled HEX file that came with the default code) the way it's supposed to: joystick forward, robot forward. Joystick backwards, robot backwards. Joystick Right/Left: robot turns right/left.

Then, after any change in the programming, after compiling with MPLab and downloading with IFI_Loader, the robot controls become screwy. Joystick forward: robot turns right. Joystick right: robot goes forward.

This isn't a problem with the code, as I can put just a single small change (changing a variable name) in the code and this will happen. Does anyone know if this is a compiler/compiler settings problem, or an equipment problem, or something completely different?

Have you tried recompiling the code without making any changes and then downloading? (Although there shouldn't be any changes between the default hex and the default code... Should there?)
