So, MicroSoft has gone and done it to us again... or at least me... :unsure: Last night there was an update to Windows 10, afterwhich RST freezes. Whenever I run RST it opens fine, but as soon as I click a button, like to add a tone, or even any of the menu items at the top - File, About, Config, the program freezes. I downloaded a fresh version 2.7.0.0 and it performs fine. I can't send a log file, as it is not generating one, there is no exception error message. Is anyone else encountering this issue? Thanks for your help, Tysylio
