This was fixed in 4.2. There is also a fix for 4.1 was that never released, but I'm going to send it to you now.
Looking back through our logs, I see that this was fixed while we were working on 4.2 and 4.3. I merged the fix back to the 4.1 support branch with the intention of releasing 4.1.26 on both Mac and Windows, but 4.1.26 on Windows had new problems with plugin compatibility so we couldn't release it. By this time it was slowing us down trying to maintain 4.3, 4.2 and 4.1, so when I fixed the plugin issue we decided to focus on 4.2 and 4.3. But it was a mistake not to release 4.1.26 on the Mac.
