I came across two problems. first, I am unable to type some specific letter, like upper case R,E,+ and so on, but I can type other upper case letter like upper case T. If I am trying to type, they will leave a square with x in it on the screen At the same time, I have no problem typing these letter in other medium.
secondly, I am trying to insert a table to the pdf file, but I cant find an option on the edit bar or insert bar. so I have to open microsoft word and make a table there, then change it to pdf format and insert it to he current page, seems rather inefficient. Is there an easy way of doing it?
specs: windows 8.1, lenovo yoga 11s, adobe acrobat pro.
