Just an FYI... 1) I originally had the -singlesel as the last option in the list (after -style) and the problem still existed. 2) When I first started this little project I was running on an older version of Win32::GUI and it did not generate any depreciation warnings. It wasn't until I updated to 1.03 that I saw the warnings. The warnings when generated look like this: Win32::GUI: the -style option is deprecated! at C:/Perl/site/lib/Win32/GUI.pm line 603.
It didn't tell me the line of my code that the -style option was depreciated and since I have a number of places where the -style option was used (not always in a listview) I wasn't sure which one it was complaining about. Thanks again for the help.

Several things to learn from this: (1) Short, complete examples are not just for the benefit of the audience that you post to; they often lead to solving (or at least narrowing down) the problem. (2) That's probably one of the reasons that the -style option generates a 'deprecated' warning (you are running with warnings on?) And for reference, the options that I've left above all do things with the control's 'style', and are processed in order. All the options except '-style', either add or remove style bits from a mask. '-style' clobbers the mask with a fixed value - it's useful if you know what you're doing, but dangerous (as you've discovered) otherwise. There are a number of ways this could be re-written so that it works, the easiest would be to move the -singlesel option after the -style option - but note that none of the styles used in the -style line are required by modern Win32::GUI versions: WS_CHILD and WS_VISIBLE are default options for a listview (and most, if not all controls), and I'm not sure what, if anything, setting bit 0 does. Glad you've sorted it. Regards, Rob.
