E mail client is not displaying all information;

Today my E mail client is not displaying all information; the options under menue are truncated to the first 2/3 letters, the description of E mails is mostly missing as are the description on the areas for clicking ‘calander’ for example ( although it’s still there if you click the correct grayed our area - but again calander entries are incomplete/not visible). Can anybody please help ?

Eventually got this sorted via a reboot !!!
