I seem to have frequent issues with the update manager software. For each of the last few updates I have ended up downloading the entire program and doing a new install. The update manager shows that I have an update available for logbook pro (1.9.8), but if I select it the install and download buttons remains grey and I am unable to install the update. I get the same result if I check for updates via control panel or via logbook pro. I have 188.8.131.52 installed now.
