I've never experience such poor performance, it took me more than 3 days to complete a simple logo because Illustrator is extremely slow, full of bugs, pixelated vector, invisible layers wont go invisible, crashing without saving even when I have saved my preferences to save files when crash occur. Indesign has been giving some issues too but I didn't really had the time to deal with the app to figure it out more. I just wish Illustrator would work smoothly every time I work on it, is extremely painful to waste all that time trying to figure it out what is going on. I'm also having issues exporting PDF's they won't export as PDF but only as a single JPEG each artboard, while exporting a PDF some pages came good another in a different size but when checking the page size on indesing they all have the same page size, so how is it possible that just one page will show up on a different size.
