I am unable to select as Input Filter Epson Stylus Color (UP). After I
press OK button on Configure Filter Screen I get Error: Bad listbox
index"": must be active, anchor, end, @x,y, or a number.

If I press Stack Trace:
bad listbox index "": must be active, anchor, end, @x,y, or a number
    while executing
".sf.f6.list get $colindex"
    (procedure "LOCAL_select_filter" line 466)
    invoked from within
"LOCAL_select_filter .e.v10"
    invoked from within
".e.autofilter invoke"
    ("uplevel" body line 1)
    invoked from within
"uplevel #0 [list $w invoke]"
    (procedure "tkButtonUp" line 8)
    invoked from within
"tkButtonUp .e.autofilter"
    (command bound to event)

After that I press OK and Configure Filter Screen do not respond to OK or
Cansel buttons. I should to Annihilate that window to get control over
printtool.
