I'm a long time slickedit user (since late 90s) and am getting increasingly frustrated with the quality of slickedit. My current stupid bug is that the find box can be slow to come up, slow enough that typed text goes to the current buffer instead of the find dialog. I do Control-F, Control-V to search for the current contents of the clip board all the time. Fairly often the pasted text goes to the current buffer instead of the find box. This is under Linux on Debian Wheezy.
Also ever since I upgraded to SE 2013, it hard hangs whenever I create a new project. I have to kill it and restart. The new project is there and works afterward.
I used to be a strong SE supporter, not anymore. Of the small number of people I know who continue to use SE, none of them would recommend it.
