I have installed Open CPN
on my win7 / 32 bit pc and it initially works fine with CM93 charts
. It continues to work after rebooting, at least for a few goes.
But then, for no obvious reason it develops a glitch. When I try to open it the program icon appears in the Windows desktop
taskbar but the program does not open on the main screen
. The glitch occurs whether I try to open by double clicking on the desktop
shortcut or by right clicking and then selecting "OPEN" in the drop down menu. And if I try the same methods having selected the program in the PROGRAMS menu.
Trying to access it using the icon in the Windows taskbar does not work either. All that happens is that a small window appears attached to the task bar showing the opening screen
of the program, located on the chart that I had open when the program was operating properly before I shut it down the last time. But that small window has no functionality, i.e. one cannot operate Open CPN
If I uninstall and then reinstall the program it works fine once more, only for the same problem to reappear after a few uses.
Any help gratefully received.
