Error when opening new windows

Hi,
I have this issue that GoWrite2 gives some error when I try to open new windows. This isn't something that happened before but I'm not sure when it started but I did update to version 3.2.0 thinking that might fix the issue (which it did not).

Usually I can open some new windows right after I start the program but after awhile it will show an error prompt and the log instead of opening a new window. I mean the main window with the go board, I can always open some preference/options windows. It doesn't seem to matter what I try, I can never open a new window unless I first close the program and kill it in task manager.

Here is the error log:

Re: Error when opening new windows

Hi,

It seems your gowrite settings are somehow damaged.

Problem relates to what is show as label for main continuation of the game. The code around this looks bad, and can fail multiple ways. There are probably quite ancient bugs, need to dig this a bit more.

You can fix the problem by renaming (or deleting) file .gowrite\gowrite31.cfg to revert gowrite to default settings.

regards
Lauri

It does seem to work with a new gowrite31.cfg. Thanks!

I noticed that the property "gowrite.gui.view.mainvariation=" was followed by a null character (i.e. "\0") in the cfg file.

I don't encounter the problem when I only change this property to "Z", following the new config file, and I do encounter the problem when I change it back. The problem only seems to occur after opening some files and maybe jumping into the middle of the sgf tree, which makes it unclear when exactly it will fail to open a window. So I tried to change it back and forth a couple of times and the result was always that there was a problem when "gowrite.gui.view.mainvariation=\0" and not when "gowrite.gui.view.mainvariation=Z".

Hope this is useful information :)

Thanks for analysis, this clarifies the problem.

I found some broken code in variation letter selection. I will try to fix this in next version.
