Version 4.1.6 (Build 412)
After executing for a while, the program was in a standby state. Suddenly the Invalid Access to Memory dialog popped up. After clicking on OK, the dialog reappeared about every 5 seconds. In between, it was almost impossible to click on any other function or menu before a new dialog showed up. Finally, I was able to access the Protocol information. Surprisingly, the dialog stopped. I was able to transfer files as usual. I have had several "Invalid Access to Memory" popups in the past. Usually, they are after the operating system has been running for a while (probably more memory used but never freed). In these caess, the program never starts working properly again. so this time was odd that WinSCP settled down.
