Narrative:
Traffic was heavy (18-19 aircraft). I had many conflict alerts that were not pertinent. I was working two aircraft inbound to tus. I handed off the inbnds to sector 47 (low altitude) and switched them to low. Sector 47 handed off medium large transport X to me and switched the aircraft to me about 2 mins later climbing to FL230. I waited until the aircraft passed the first inbound then climbed medium large transport X to FL270. I could not see the second data block due to data block overlap. There were about 8 aircraft over the same area. When the conflict alert activated we had lost sep already. No warning was given. The data block on the second inbound (large transport Y) could not be moved because the D side had moved it to a slant zero position. To correct. D side personnel should not be allowed to do right side functions. When working aircraft inbound and outbnd, one sector should work both aircraft until they pass. Conflict alert should be updated to be of some help not just to tell on the controller.

Title: ARTCC RADAR CTLR CLIMBED AN ACFT WHICH RESULTED IN LESS THAN STANDARD SEPARATION WITH ACFT HE HAD HANDED OFF EARLIER TO ANOTHER CTLR.
Narrative: TFC WAS HVY (18-19 ACFT). I HAD MANY CONFLICT ALERTS THAT WERE NOT PERTINENT. I WAS WORKING TWO ACFT INBND TO TUS. I HANDED OFF THE INBNDS TO SECTOR 47 (LOW ALT) AND SWITCHED THEM TO LOW. SECTOR 47 HANDED OFF MLG X TO ME AND SWITCHED THE ACFT TO ME ABOUT 2 MINS LATER CLBING TO FL230. I WAITED UNTIL THE ACFT PASSED THE FIRST INBND THEN CLBED MLG X TO FL270. I COULD NOT SEE THE SEC DATA BLOCK DUE TO DATA BLOCK OVERLAP. THERE WERE ABOUT 8 ACFT OVER THE SAME AREA. WHEN THE CONFLICT ALERT ACTIVATED WE HAD LOST SEP ALREADY. NO WARNING WAS GIVEN. THE DATA BLOCK ON THE SEC INBND (LGT Y) COULD NOT BE MOVED BECAUSE THE D SIDE HAD MOVED IT TO A SLANT ZERO POS. TO CORRECT. D SIDE PERSONNEL SHOULD NOT BE ALLOWED TO DO R SIDE FUNCTIONS. WHEN WORKING ACFT INBND AND OUTBND, ONE SECTOR SHOULD WORK BOTH ACFT UNTIL THEY PASS. CONFLICT ALERT SHOULD BE UPDATED TO BE OF SOME HELP NOT JUST TO TELL ON THE CTLR.
