Since a year ago, regardless of the adminer version, altering the table freezes the browser for several seconds.
1. click Alter table
2. Make changes
At p. 3 the browser freezes and becomes unresponsible, in bad situations up to 5-10 seconds. In good situations there is no freeze at all (or it's very short) Tested with FF, Chrome and IE on many computers. Any click in the frozen browser windows whites out the window. Waiting times are much longer with tables that has a lot of fields.
Is this a java problem or it's adminer?? Anybody else has this problem? It's very annoying...
I can provide a screenshot video also.
