double-click on "save" after editing table causes crash

[andipfaff]

Steps to reproduce this issue

1. start HeidiSQL, connect to a DB
2. click on a table (preferably a big table) in the tree
3. edit something in the table structure
4. Click twice on save

Current behavior

HeidiSQL crashes on some PCs

Expected behavior

HeisSQL should not crash

Possible solution

The save button should be deactivated after clicking

Environment

Use a table filled with hundreds of thounsands of records in order to have time to click twice before changes ar done by the server

• HeidiSQL version:

using latest nightly version

Can confirm this. Though the save button is disabled later, but too late. Should be done as the first thing after a click on it.

Should be impossible to click the save button twice in the next build.
