Histogram not displaying data with multiple logs

[snowrx]

My MegaLogViewer HD 4.2 .06 has stopped displaying data in the histogram cells when I load more than two logs. It will show or play the data track if I click on the log display below, but no histogram data or color. The scatter plots are populated just fine with multiple logs loaded. HD used to load 5 or 6 logs and display histograms, now it balks at more than 1 and I have to close the program to get it back to displaying even one file.
I'm missing something, is there a limit on size or number of logs you can analyze?

What size logs are you loading?
Nothings changed there for a while, The limit is really just the amount of memory allocated to it.
The histogram itself doesn't know anything about the number of logs loaded to the data set.

I actually had the same problem a few days ago. I also couldn't select RPM on the X-axis. Everything worked fine again after I reinstalled it.
