I have had a handful of people (probably about 8 in 300 users) report a weird problem to me that I can't reproduce and can't find a solution to. What happens is when they enter a value into a textbox and then change focus to another input, the value is deleted. My inputs inside the panel look something like: <textarea rows="4" variable="#ui_st_c_custom" fillwith="value" placeholder="" class="input-large"></textarea> I have tried removing the placeholder as I thought that might cause issues with ubots html rendering but no difference. I have made sure people have the lastest .
