Studio problem, "invalid opcode"

2007-06-16 by Dave VanHorn

Starting off on another crash project.. 
Downloaded the latest studio.

File assembles ok, no warnings or errors, but whenever I do a call or
rcall off the main loop, I get "invalid opcode 0xFFFF at address 0x00f020 

The address is always the same!

I looked at the lst file, and the code looks normal.
The call it's having problems with is: 0001A2 d087

Stack IS set up, and hasn't been corrupted.
I can add another call in front of this one, and I get the same problem.

Very odd.

Anyone seen this, or have ideas?
