This is now the 2nd or 3rd time in a month that TWS deletes ALL pages on the platform. I hope IB is listening and resolves this serious problem soon. At least they could tell the user, save "x" file and if it happens, fix it this way. I'm just sick of retyping all the symbols again! I have version 820.2 This time I'm wiping TWS from my computer and starting fresh to see what happens.
