[...] cat_sel_cancel_btn are equal) it should execute this case block, printing something with "point 5" in it; however, it continues to the "case else" and now the value of the CONSTANT "cat_sel_cancel_btn" HAS CHANGED! In the following code pf() is a print procedure which does nothing but print what's in the argument. I rewrote the code to use if/elsif statements instead of using switch blocks. [...]
I tried the code below using a recent 4.0.6 and a 4.1.0 32bit on Win10 64bit
