Some time ago, a feature was added to optionally increase the size of the toolbar buttons in GTViewer. Originally, this feature was intended to make it easier to select the buttons when using Tablet PC or any other laptop with a stylus or pen. The buttons are only slightly larger, but the size difference does make selecting the individual buttons much easier since the target area is larger.
The screenshots below illustrate the different sizes of the buttons; the top uses the regular sized buttons and the bottom uses the larger buttons. The Zoom command is activated in both screenshots and can be used to more easily compare the size difference:
With the lackluster success of Tablet PC in the marketplace, this option was never integrated into the user interface, but it can still be used by setting a registry entry. Find the HKEY_CURRENT_USER folder, then Software, then Graphics Technologies Inc, and finally GTViewer. Under GTViewer there will be a Settings folder.
Add an entry to this folder called BigButton Flag. Make it a String value and then set it to 1 (setting it to 0 will be the regular sized buttons):
Run GTViewer and you should see the larger buttons.
You can also create a .reg file like the one shown below and run it:
Windows Registry Editor Version 5.00
[HKEY_CURRENT_USER\Software\Graphic Technologies Inc\GTViewer\Settings]
