TT crashes COM port while entering LOG file name
While connected to a bluetooth module (ie HC-05) via a COM port (ie COM4, 115k 8N1) and receiving an ASCII text (ie 250bytes per second, .csv data) and trying to LOG the incoming data into a file, when the selecting/writing the name of the log file (File->Log->Save window) takes longer than, say, ~20secs, the incoming text in the TT window freezes and the COM port is not accessible anymore. Opening the COM port shows error 79.
Windows 7 Ultimate, TT v4.104.
Not only while entering the file name, but always when the File dropdown is opened for a longer time, also with 50 bytes/sec input..
