Hi all,

sorry if this has already been posted, but I couldn't find any relevant topics. In our recent online studies, we have noticed that the mouse cursor may disappear on survey pages with textboxes when a character is entered into the textbox. Although moving the mouse usually resolves the issue, sometimes the cursor remains gone, meaning participants cannot click on the continue button. Until now, we have solved this issue by including a note that this issue may occur and instructing participants to use the Tab key to switch to the Continue button and the Enter key to continue. However, the issue has now occurred in a textbox which accepts Tab as an input, meaning one cannot switch to the Continue button. This is obviously a problem - although my own testing indicates that the mouse cursor reappears when one blindly moves it over a survey element (the textbox or the continue button), I'm not sure if this is the case on every system and it is also a suboptimal solution for our online studies, where participants may not wait to read workaround instructions and instead drop out. 

I'm attaching a script with this issue. I should also note that the mouse cursor seems to disappear consistently for me when I enter a character, but it mostly reappears as soon as it's moved. In about one of five cases up to now, though, the mouse has remained gone until I hit a survey element on the exact same system with the exact same setup. Is this a known issue and is there anything I can do about it? I suppose I could include hidden stimuli that cover the entire screen if it's just a matter of making the mouse hit a stimulus element, but I would prefer not to have to if possible.

Thanks,
AK

A quick update: I just tried inserting dummy <shape> elements that covered the whole screen into the surveypages with textboxes. The issue remains: the mouse cursor disappears when I type any character into the textbox and sometimes completely fails to reappear until I randomly hit a survey element. Mousing over the shape did not resolve the issue, so it seems to be something to do with having to actually mouse over surveypage elements. When I inserted the gender (dropdown) question from my pasted script into the age surveypage, the cursor reappeared when I hit the dropdown menu (causing it to glow slightly, as is normal on a mouseover).

Is there any knowledge at all about this issue? It has been reproduced on one computer that I know of (a research assistant's) and I'm nervous that it could cause problems in our online surveys.
