To illustrate, here is a gif showing some basic actions i tried carrying out within my example dmf file Gif Here.
Numbered Steps to Reproduce Problem: Covered above in gif.
Expected Results: To be able to have all actions take place on the correct control naturally (without needing to use the controls menu), i.e the control over which my mouse pointer lies, that is also the closest to the top in tab order should always get priority.
Actual Results: As seen
When does the problem NOT occur?: Never, i don't think.
Did the problem NOT occur in any earlier versions? If so, what was the last version that worked? (Visit http://www.byond.com/download/build to download old versions for testing.) :unsure to be honest, but i did notice this happen while i still had 506.
....yeah that's about it.
