TListview Icons missing

I have an app with a TListview I add items to it and connect it to a TImageList using each item's ImageIndex property. I can see the icons nicely at the design time and even on run time on my computer and other computers.

Now comes the bad part - on some computers I am unable to see the TListView icons and only the text appears. The items _do_ get "hottrack'ed" when the moust pointer is over the place where the icon should've been.

What's that?!

Yes, my customer's computers are old (Pentium/133) and running old win95.

I sent the file to my customer, I'll check with him if it fixes the problem - if it does - you get the points.

Others - you can still offer solutions.

how about re-compile the project without optimizing code?

I have an experience to solve same case like you:
I just remember that I uncheck [Compiler-CodeGeneration-Optimaze] & [Packages- Build with RunTime Packages] in the [Project-Options] and it works.

Actually, I doesn't know what it did totally.

it is so strange.
we have 1 program running on win95/98 (some 95, some 98).
one day, some users report why the layout of his program[some nice icon are missing] is different from his neighbour.
we check the history of program-upgrade and found the size of current delivery is smaller than that if pre-version.
note: if we run the pre-version on the platform that has problem, it is ok!
.....
Finally, we try to uncheck [Compiler-CodeGeneration-Optimaze] & [Packages- Build with RunTime Packages] in the [Project-Options] and the generated executable file regress and it works for all clients' platform.

is it strange? we have not time to study the reason but it solved.

inthe - you were right from the beginning, I got a call from my customer saying the COMCTRL upgrade solved the problem!

Thanks a lot!

others: There's nothing wrong with the optimizations of Delphi.
