I have just downloaded and started using 4.0d beta 2. Logos consistently crashes within a few seconds after I start a search of any kind. The first time I experienced this crash, I did a search on a Hebrew word in the ESV, and while it was searching, I clicked on the box in the top left hand corner of the panel to see if the "copy to clipboard" had been included in this beta. It has, but the program crashes before I can use it[:(]. My log files are included. FYI, Logos was still indexing at the time.
