Experienced the following glitch when installed new TWS version on Linux machine. It is looking for jts.ini in "c:\jts\jts.ini" and of course doesn't find it. As a consequence, TWS couldn't even log in properly. Solved this problem the following way: looked in the directory where my TWS is installed and saw a file "c:\jts\url.properties" there. By analogy copied jts.ini file in the name "c:\jts\jts.ini" (all is single file name). All works just fine now! But still, IB, would you be so kind to somehow fix this in future, as this kind of discrimination in TWS code as not seeing .ini file which doesn't look like Windows one is a bit annoying... Hope sharing this experience helps someone who might have the similar problem.
