I have recently fixed the second issue you got. The first one might be fixed since re-coding those troublesome methods. The last one is hard to say, that menu option should have been inactive if there was no path, I'll look into the matter. You might have been able to catch it in an undetermined state. See, it's good of you to catch these, I have a certain... process I got used to.
It's like play testing a game. I'm bad at play-testing my own games because.... I know everything! I know if a chest is not working or a door is inactive.
The editor is only for x86 systems (or above), so it's okay if you run a 64 bit computer (I run 64 bit as well). I may not do an x64 version since the libraries I use do not support x64 out of the box.
Edit:
I have released v1.1.2.0, which has many, many improvements.
- The task editor is now a standalone plugin
- The image editor can now properly resize an image.
- The Map editor doesn't show full tile selection when on a tool other than the Pen tool.
- The image editor is flagged as dirty when editing images.
- The script editor now has font support (now you can change the font). (not yet the spacing... but soon).
- The Sphere Config is now not able to be clicked on if you cancel out of the initial settings dialog.
- The Scripts menu item only shows when a scriptbox is active.
- The Plugin system now let's you style your own dock content and listview items. (still not ready for full-on plugin creation).
- Made the project list view load a thousand times faster now. Yes, a thousand or a million depending on the # of files in your project.
- Fixed error with empty paths in multi-path game box.
- Added description text to folder browser in game paths and sphere folder dialog boxes.
- Fixed View menu from listing empty forms and not reordering the items in the list. - The default .NET code always sucks.
- Added tile removal back into map tileset editor. (Was off for the last few versions).
- Made image editor remember the blend mode when switching between images.
- Updated ObjectListView to latest version.
- Set Cursor to a loading cursor when loading projects, not that it matters anymore.
Still a million more things to do!
Edit2:
Just to let you know, the task list is definitely something you can't 'port over', so remember your old list, and be prepared to rewrite it. After this though, there is no more updates to the format.
