When opening a TDM model with the monitor set to different screen resolutions, TDM resizes the objects in relation to the page size, which looks confusing as the screen resolution and the page size are not related to each other. In a 1024x768 resolution, the objects are resized so the layout is far more cramped and also crosses the page boundaries. TDM doesn't reposition the objects so in some cases the objects actually overlap each other.
The fonts are the cause of the problem. When the screen resolution is changed, the width of fonts also changes, causing the re-sizing issue. For different screen resolutions, objects in TDM3 are being resized. However, this is applied only if the Recalculate Size option is selected for the objects (see Object Format).
Waiting for fix in a future release TDM.
