Your modifications at the <switchinline select="sys"><caseinline select="MAC"><emph>%PRODUCTNAME - Preferences</emph></caseinline><defaultinline><emph>Tools - Options</emph></defaultinline></switchinline><emph> - $[officename] - Advanced</emph> tab page will be used even if the Java Virtual Machine (JVM) has been started already. After any modifications to the ClassPath you must restart $[officename]. The same is true for modifications under <switchinline select="sys"><caseinline select="MAC"><emph>%PRODUCTNAME - Preferences</emph></caseinline><defaultinline><emph>Tools - Options</emph></defaultinline></switchinline><emph> - Internet - Proxy</emph>. Only the boxes "HTTP Proxy" and "FTP Proxy" and their ports do not require a restart—they will be evaluated when you click <emph>OK</emph>.
