When I start TinyTERM, it doesn't open. It puts a button on the Windows Taskbar, but there's no window and no error messages.
The window position and size information for TinyTERM has gotten corrupted. You can double-check that by right-clicking the TinyTERM button on the Taskbar and selecting "Maximize." TinyTERM should open to a full-size window.
To fix that, edit the .tpx file being used in Notepad. Search for the following two lines, which will be one right after the other:
They'll both be set to very high numbers, or they'll be negative numbers. Change each to 100:
Save the changes and close Notepad. The next time you start TinyTERM, it will open in a normal window. It may be too small, so resize it as appropriate.
