Bug: HeidiSQL doesn't show anything when I try to open a connection

It runs some process but It doesn't show on the screen. Any ideas why?

The only way I can get this is when, sometimes, I forget to start my ssh tunnelling. Then I get an error window stating "Can't connect to SQL server on 126.0.0.1 (10061)". It pops in the background, behind all other windows, with no icon on the taskbar, but I can definitely hear a sound. Also, you are running a very old version - 5599. The latest is 5753.

Probably the restore-tabs feature waits too long for opening a file which is locked for some reason.

You can testwise disable that restore feature:

• exit all HeidiSQL instances
• start regedit.exe
• go to HKEY_CURRENT_USER\Software\HeidiSQL
• create a new 32bit DWORD value
• name it "RestoreTabs", and give it a value of "0"
• start HeidiSQL

Thanks. Now everything works as expected.
