I just went into UTRS for the first time today to check out a block relating to one of my actions, #18351. I found it impossible to view the text beyond the ellipses with my screen reader. I informed the reviewing admin, who told me that the full text is displayed in a new window that scrolls when clicked in. This is unhelpful for users like me because screen readers have no concept of scrolling in to anything ... many of them show a virtual representation of each webpage which can be somewhat different from how it looks to a sighted user. I tried it with all the combinations of screen readers/browsers I have (JAWS/NVDA and FF/IE) in Windows and I couldn't get it to work reliably. The only way I could view the full text of the log actions was to view the HTML source. Even something like an expand/expand all link near the log actions would make things much easier for me.
