c# - Program only works correctly in debug mode -

here previous question, if want further information regarding current problem:

winform: inherited panel wont autosize

if don't want read through it, i'll give general information:

• i'm not working directly via programme, i'm editing specific dll, used programme
• that means, don't have access source code of specific programme
• that means have fix problem via changes in dll, - mentioned before - used programme.

what found out far:

• it works without problems, if attach programme dll's source code in vs2015.
• but has glitches if build code , copy dll programme's folder - that's actual problem: somehow shrinks tablelayoutpanel half actual size , weird glitches in other half of actual, in normal start somehow not used, size.

what tried out:

• i changed size manually, not via "dock = fill" or "autosize = true" , worked. that's, may know, not best solution , want use it, if there absolutely no other way around it. no 1 likes hard-code.

• i tried inherit parent's size via:

  this.tablelayoutpanel.size = this.size; and
  this.tablelayoutpanel.size = new size(this.height, this.size);

so guys have ideas?

okay, did not figured out why debuger worked , release/debug build not. forced redraw on tablelayoutpanelmainwith application.doevents(). never tried out before, because invalidate() + update() or refresh() did not work - like: okay, wont easy, forget that.

but after trial & error , lot of time...well, working 2 weeks on it...i tried simpliest thing out , yeahy, worked!

anyways, thank help, guys. appreciate that.
