TLMDGridPickListChooser bug

Sol.E. s.n.c.

I have used
aPickList chooser in a CBuilder 10.4 application, but when I click on the list
open button the result is a multiple “Range check error”. This problem disappears
if the application is compiled for the Win32 platform or if the appearance
style is let on “Windows” default, any other custom style is not supported.
