How to disable auto-update checks?

I use smartftp 1.0.6 and do not want to update as 1.5 hogs 100% of my CPU and makes it hard to even use my mouse. Problem is, everytime I start smartftp it annoyingly informs me of an available update and opens internet explorer. How can I disable this? Thanks.

I don't know how to disable the updater, but don't you rather want to help us resolve the issues you have with 1.5.x? Please post a bug report with full log / copy of the system information from the help -> about menu. I'm using 1.5.x without any issues.
