More Output Preview prefs/fixes

as long output preview box open user's cursor displays crosshairs, regardless of tool being used. annoying because user doesn't recognize tool using unless closes output preview box. users don't want have keep opening , closing output preview box. my suggestions: make button in toolbars "activate" output preview window. way window stay open time, when not "active" users should still see cursor selected tool. (maybe output preview still display percentages when "inactive" change cursor crosshairs when active.) slight clarification: there toolbar button opening , closing output preview window. users want button activate or deactivate window, not open , close it. (clicking on window should make active, clicking on tool should make inactive again.) More discussions in Acrobat Feature Requests adobe

ciao, sapreste dirmi grandi linee come vengono trovati dal codice php giusti riferimenti tra vari file css? ho visto che ci sono molti file .css e mi sto chiedendo come faccia il codice sapere dove prendere dati giusti tra tutti questi file. immagino abbiate capito oche non ne nulla  il fatto è che vorrei cambiare colori o altri parametri del mio sito ma non riesco trovare il css giusto, ho provato anche con le estensioni di firefox per css ma alcune parti sembrano non essere associate css mentre dal codice php sembrerebbe che ci fossero richiami classi css. sapete istruirmi al riguardo? nel caso specifico vorrei cambiare pulsanti standard di j! e vm con altri ma non riesco trovare la classe button associata ad essi. scusate la marea di boiate che sicuramente ho scritto e vi ringrazio!  se intendi lavorare sui css dei frontend apri il file index.php del template in questione e nell'head del codice (la prima parte) vedi collegamenti ai fogli css utilizzati Board

Current reading triggering alarm
