Online Tracker - Bug with Protractor measuring tool
John Marrin
2 Posts

Dear All

I have a few students that are trying to use the online version of tracker, and while most features seem to work nicely, the measuring tools doesn't seem to allow the selection of markers to track when attaching points (no drop down option - see attached screenshot). Is there anyway around this? Or perhaps there is eomthing we are not doing correctly?

Thanks in advance for any help that can be offered.

Best wishes
John

Thanks to Bob Hanson's work debugging the Java -> JavaScript conversion library, the Protractor bug in JS Tracker is now fixed.
