I am experiencing the weirdest thing I ever encountered in Delphi... and so far I cannot explain it. And also I cannot solve it.
Some components (usual ones like CheckBox, ComboBox, Buttons, MessageBoxes) seem to have their caption invisible. So the text is there because I can see the surrounding dotted rectangle around it when they receive focus. Also for Comboboxes, they dropdown in the list and the list is as long as it should be but there is no text there... if I browse through it and select one of it's invisible items... the combobox shows me the text that was supposed to be in the dropdown list.
Also some ShowMessage boxes do not have the message body, and neither the buttons on the showmessage box. So the ShowMessage and MessageDlg... shows me a form with no text on it, and 1 or 2 buttons (Ok Cancel) but the buttons have no text on them . Everything on the standard ShowMessage and MessageDlg is empty.
The interesting thing is that I have to very similar forms that contain almost the same components (anyway the same component types like Edits, ComboBoxes... and so on), so there are no other types of components on them. And one of the forms works like a charm, the other gives me headackes.
The most interesting thing is that this behavior only seems to appear on certain computers. On my own ones they work great. But on one of my client's computers (3 computers) don't.
At first I thought maybe it's something wrong in the registry... but if it were, then all the forms that have MessageDlg and ShowMessage , Checkboxes and Comboboxes on them should have the same problem, but they don't.
Another thing: On these two particular forms that are 98% identical (the one that works and the other that doesn't) half of the components are created in design time and the other half are created on runtime.
Also another thing is that on both of them I use standard Delphi VCL components plus a Jedi component called jvScrollMax (where I create on runtime some components). But since I do almost the same steps in both forms I don't think that this component is to blame.
So this is probabely something internal in Delphi, but I cann't figure it out.
