Just to notify you that DbVisualizer 10.0.3 has just been released with a fix for the issue you reported.
This is a better screenshot showing where tabs are used.
Thanks for your email.
We will look into this.
I'm using tabs to layout my code in the SQL editor and during execution of commands they are shown in the column "SQL/Command" in the log. The tabs seem to be missing in that textual output, whereas spaces are present. I've attached a screenshot to show the differences. That column would be more useful/readable if tabs would at least be changed to spaces.
