           Summary: Applying new settings to the ASCII datasource takes
                    ages
           Product: kst
           Version: 2.0.0_devel
          Platform: unspecified
        OS/Version: MS Windows
            Status: NEW
          Severity: normal
          Priority: NOR
         Component: general
        AssignedTo: kst at kde.org
        ReportedBy: nicolas.brisset at eurocopter.com


Version:           2.0.0_devel (using unspecified)
Compiler:          mingw delivered with QtCreator 1.1.0
OS:                Windows 32-Bit

For some reason, hitting "OK" in the ASCII configuration dialog called from the
"Configure..." button in the first page of the datawizard takes *awfully* long
(ca. 10 s). 
This wasn't the case not so long ago and is really penalizing. It should be
fixed. 

Also, and this may be related, it seems that changing the configuration of the
datasource involves many calls to some functions (I put a trace in readGroup
not long ago, and it showed up 3 or 4 times in a row). I think there is
something suboptimal in the mechanism. See also the discussion to bug #215931
for that point, I am still not convinced that the sequence is optimal.
