Tilemap Editor (untitled)

[PK8]

Thanks a bunch! I've been playing around with your editor for a few days now and I'm really liking it.

However, I came across a few bugs.

• I made a graphic and gave it a name (let's go with "tileset.png"), loaded it up, messed around with it a bit and saved the map as an image (dunno if this information helps but I'm putting it out there). I did a massive edit to the tileset graphic and overwrote "tileset.png". I started a completely new map, I loaded the graphic and somehow I'm seeing the original tileset graphic I did instead of my recent edit to it. Really.
  
• I found another bug where I can't seem to change the tileset graphic and property settings after starting a new file. Here's a way to reproduce it: Go to properties, load up a graphic and set the properties, click "Ok", click New, go to properties again, set up the graphic, tile height/width and map height/width and save changes by clicking "Ok". That doesn't seem to be working the second time around.
  

Also, quick question: Any features for the miscellaneous tab?
Edit: Wait, could these bugs be considered bogus?

Also, about the first bug, I didn't realise the original tileset graphic would be copied over to the Tilemap Editor's "Resources" directory. I was loading my file from the Desktop. I deleted the graphic from the "Resources" directory, I think I fixed my little problem.
