Till today morning everything was fine. When I opened a word file containing many equations it took time a lot of time and at last no equation were previewed. It showed object1, object2 and so on. If I double click on it editor would open up and for that much time it will preview equation. Once I close editor again equation is gone and it shows object1…
Same issue is with image files as well. None image are viaible it shows image 1 imagr 2 and so on.
What can issue?
