[@emperor] I didn’t want to write too much, but believe me, before publishing previous post I spent a few hours on reinstalling, restarting computer and cleaning HD & registry to be sure there are no traces of previous installations. Result always the same – red/green markers don’t even appear regardles of how many times I click on the markers icons. Even wanted to download previous version-8 trial, to check if it would work on my desktop, however it is unavailable. Most probably the latest v9 has a bug causing problems on Win10 32bit.
