Am just going to post this report as recommended in the howto section.
1. WinSCP v5.2 Beta build 3157
2. Just did an upgrade(well almost a week now)
3. Using Win 7 Ultimate 64bit
4. Using FTP, Commander interface(awesome)
5. I must say this version works flawlessly and is very fast, just a minor bug on the end users side. Whenever I use the scrolling feature on my laptop's touchpad, I get an invalid access to memory error. I have verified that this does not happen with a regular mouse when scrolling with the wheel. I also added a screenshot below.
Besides this negligible error, v5.2 is the best and fastest version of winscp i've ever used, hats off Martin.
