If I open a data log file with (just double clicking on it from Windows Explorer), I'm sometimes not able to see the data. When this occurs, most of the PIDs which were logged are missing from the PIDs tab. The map/dashboard tabs have those parameters accordingly crossed-out.

The files are larger than 3000 frames. It tends to be less likely to have a problem if I click the PIDs tab first after saying "no" to the do-you-want-to-replot all data dialog. This is not always the case. Another factor may be which tab is initially displayed (i.e., which tab was last selected when the program was last quit).

Happy to attach a log file, post screenshots, etc, if desired. Not a huge problem now that I can workaround it.

Please bear in mind the post count, I'm brand new to this, so I could just be doing something wrong.
