I close snagit after closing everything from the recent tray. When I open the snagit editor from the menu it opens the last item I had open, it should open a blank editor but it always tries to open the last one. This is on 13.1.2 Win 7 Pro 64bit
There seems to be some other problems related to window opening. This new build is buggy. I'm on Win7 64bit. For example I dragged the editor to the edge of the screen to make it full screen. Then the editor window disappeared completely and clicking the icon would not open it up. I had to open Windows Task manager and end the snagit processes and then I was able to relaunch it.
I can't duplicate this behavior on command but another time the editor vanished like this and I rebooted to get it back. So 13.1.2 is buggy. Maybe the programming has memory leaks or isn't refreshing the state of the window as it changes and then gets itself into an untenable state and has to be force quit. Hope the next build addresses some of these issues.
You're right, it does behave like that. I don't know whether this has changed from a previous version. I can't see any setting that affects it.
From my perspective the current action is acceptable because 99% of my work is with recent captures. But I can see how it would be annoying if your primary need is for a blank canvas.It needs to be a preference setting.
As a workaround, did you know that Ctrl+N brings up the new image dialog - that's a lot quicker than doing File > New > New Image
