I have been using HeidiSQL latest portable version for a couple of weeks with no problem. Suddenly after an overnight update to Windows 10 prerelease 200612-1734 I now no longer have any GUI for HeidiSQL. I have seen several posts on this issue from the past so I did a complete fresh install with the Windows Installer version. Still no GUI. I checked REGEDIT for "MainWin" items but there are none.
I run with 3 monitors and multiple desktops but up to now have had no issue. HeidiSQL is not appearing on any of them.
Using Task Monitor I can see HEIDISQL.exe is running in the background, but no icon appears in the taskbar when launched. It is not one of the active processes.
Any idea what is causing this and how to fix it?
