I am not sure if the previous post means a upcoming build but i did some testing with R61 and it no longer happens for Sprite, however crashes happen for basically all other objects.
The general method for a crash is:
Add 2 text objects, Select Text2 in the layout and press the Delete key. Text2 is still in the Object types folder (shouldn't be in my opinion), select it and press Delete key and you get a crash. The same thing happens with Tiled Background and the other visual plugins.
In fact the delete system seems buggy in general and does it with hidden objects also. If you add 2 Arrays click Array2 in the Objects tab and press delete it will crash the program. If you add a either a WebStorage, keyboard, Mouse, Browser etc then delete it from the Object types folder the program crashes.
I am starting to think using this history feature rather than a true delete is maybe just causing the program more problems than it's worth. I don't fully get the need to have a sprite object with no instances either as couldn't you just have a hidden sprite?
If it's going to remain it would be nice if there was a way to set a option somewhere to bypass it and just directly delete objects (Remove from the Object types folder also) when using the Delete key shortcut on the Layouts object. If the crashes/bugs get sorted it would be less of a problem but hopefully that could be possible also. FireLight2011-10-10 09:12:43
