On Windows, when the text in a custom dialog is larger than it can display, it shows a scroll bar on the side, so there is no way to see all of the text at one time like you can on a MAC. On the MAC, if you make the dialog window larger, you can see all of the text without the scrollbar.
Is there any way to make the custom dialog auto expand to the size of what it is trying to display?
A user should not have to expand the window size on a MAC or scroll through it on Windows... It should be able to calculate the dialog size and display all of the message unless it goes past the limits of the screen.
