Hi Ricardo,
We have seen this a lot, especially with the upgrades from unsupported XP's to Windows 7 or 8.1. Too much actually.
Sometimes adjusting the regional settings works because they have changed from your previous XP workstations. Could be just the different defaults because of the manufacturer. We can talk all day about checking regional settings and screen resolution magnifications, but at the end of the day, be aware that this is a known and common problem that may require revising the Adagio specifications.
New workstations may come with much bigger and higher resolution screens. Some of the screen resolutions transfer properly with adjustments to the regional settings but there is no guarantee. Similarly, the higher resolution screens often make icons and displays smaller so that users look to a higher magnification to see the screen content. All makes sense.
Unfortunately, what doesn't make sense is that the Adagio Forms are not transferable to differences in screen resolutions.
Crystal reports work fine with upgrades but forms documents such as check layouts or invoices or statements or purchase orders do not always transfer and as such need to be checked. We always budget time for forms modifications that require either alignment modifications or wholesale redesign.
In your situation, at least all workstations are upgraded at the same time. Otherwise you have a problem because you would be working with different specifications depending on the workstation, which creates printing issues in a multi-user environment. Also you have to make sure that every user printing the same forms has the same screen resolution (or magnification).
Be aware that the alignment of check forms in the specifications does not use the same alignment as live check forms so that you will need to test checks with a live check form, versus printing the alignment in the forms designer.
Best,
Brian
