Using CVSNT (2.5.03) with TkCVS, the binary file icon (stat_kb) is not shown for binary files.
The code which controls this is in dircanvas.tcl
if {[string match "*-kb*" $DirList($w:$f:option)]} {
set DirList($w:$f:icon) stat_kb
}
To have it work with CVSNT, the match expression should be changed from *-kb* to *b*
if {[string match "*b*" $DirList($w:$f:option)]} {
set DirList($w:$f:icon) stat_kb
}
