Not quite sure where to put this, but I'm having a problem with art asset importing.
To be clear what I'm talking about, I routinely drag-and-drop various map assets to the Background layer; sometimes full maps, sometimes map tiles, sometimes individual objects (though those I put on the Object layer).
I think I've occasionally noted the following problem before, but it seems to have gotten worse lately.
Usually I'm able to import a single map to the Background without notable problems. But if I'm putting something together with tiles, I can drag the first piece over to Maptool on the Windows toolbar, but attempts to continue with the successive tiles causes the Maptool icon to show the typical null symbol and a red underline, but will not expand into the Maptool window and I can't place it.
I can still do this with resizing both the Maptool window and the folder with the art assets, but I find that a little clumsy. Any suggestion as to what is causing this problem of dragging to the Maptool icon on the toolbar?
