This just started today and I can't figure out what it causing it.
When I use either the wand or color select tool in the image editor to select an area that I want to erase it immediately starts to fade and delete part of the selected space as soon as I click on it.
This is the image before I click on the green space to select it...
...and this is what happens when I click on it.
At first I thought it was just an error related to version .99 but now ALL of my versions of Construct do it. I tried uninstalling every version that I had and then I restarted and installed version .989 (which never had this problem). No luck, .989 is doing it too.
The strange thing is that when I made the "2.5d" .cap that I posted in the upload section I didn't have this problem. The only thing different than usual that I did today was I opened an old .cap and after adding some images I created a sprite of a box and I changed it's transparency.
It isn't a .cap-related problem because it happens with all of my old .caps and any new file that I create.
A few more pics, in case this helps anyone guess what could be causing this (the box select tool also fades and deletes pixels).
