[solved] Run ning up the wall problem

[Silverthorn]

I'd laugh if this is related to the space after the 158 :P
file(156-158 ): sprite\sys\rudolf_4.bmp w: 79 h: 79 row: 1 col: 3
Which I don't expect to be the cause, I just wanted to point that out.

Well, like 3rdEnemy suggested I assume that your sprite-sheet is 80 pixels high (means 79 for character + 1 for spacer (like the green lines in the template spritesheet (and I like to use parentheses))) and 240px wide. Otherwise, these sprites are randomly (or non-randomly) disappearing. Your thingy seems to be obviously a pure sprite-problem, no algorithm flaw or the like. Can you identify which sprite exactly is missing (as in putting other pic-numbers for easier distinguishablity); and, related to that, what would happen if you just change the pic-numbers to something random? Would these images still disappear?
