Can anyone confirm that this is a real bug, and not just a 'made by Lyle' problem?
If I start a project in 4.08, and add files to the project (either create new or open existing), no problem.
If I then delete a file from the project, any further attempt to add a file results in an error message. Using the key with focus on the project view window results in a "Error gettin node 20" message, and using Project>Create new file or Project>Add existing file from the menus results in an "Error selecting xml-node 01" message.
I don't get these problems in 4.07, but this is to be a Tiny13 project (which isn't supported by 4.07). And WHY WHY WHY WHY can't I use Studio 4xx to continue to do work with the Tiny15 and the 90S1200???
(beware, rant follows)
There is another thread currently running where the author has taken a fair bit of flack for criticising Atmel for releasing buggy software. I'm on his side. There is no caveat that this development system is intended for hobbiest use only, and I don't think that it is reasonable to put up with this sort of performance. I use this software for professional work, and have lost a fair bit of time on this "upgrade." This, in addition to the fact that I must now run 2 different versions of software to continue to support existing products and that the firmware upgrade to the STK500 is not bacward compatable with Studio 3.55 has left me fuming.
In anticipation of the "what do you expect for free" and "real professionals buy expensive software" comments likely to be generated, not every company has a budget for expensive development systems, and not every product justifies the expenditure.
